Try saving up and go straight for MKB. Personally I find them superior to your normal rubber dome keyboards. Some excellent suggestions are like the ones Clem1982 suggested above. I own the Aivia (with Cherry Red switches) and I personally find them to be the best keyboard I have owned thus far. Yes, they're a tad pricy though. Or you could settle for the more basic ones from Rosewill or Ducky, should cost you below RM300 price range.

If sound is a concern, you may consider Cherry Red / Brown switches instead. Blue is a bit on the noisy side, but they're excellent for typing though. On the differences between a regular keyboard and MKB, let your fingers try them out. Nothing tells you a better story.

I noticed that the Corsair K65 is TKL type, so if you want a full-sized keyboard, best to go with Rosewill RK9000. For which type of keys, best to let your fingers try them out. Some say Red is not suitable for typing and is more of a gaming switch, but I personally find them ok for typing. Guess it's a matter of getting used to.

For TKL MKB, you can also consider CM Quick Fire Rapid from lingloong (Garage Sales). For full-sized, CM Quick Fire Pro. Both are below your budget.

What brand? Try checking with the experts at MKB thread.
